- Test the claim that the mean GPA of night students is smaller than 2.3 at the .005 significance level. The null and alternative hypothesis would be: Ho:p = 0.575 Ho:u = 2.3 Ho:4 = 2.3 Ho:p = 0.575 Ho:p = 0.575 Ho:4 = 2.3 H1:p > 0.575 H : u> 2.3 H1:4 < 2.3 H1:p < 0.575 H :p + 0.575 H1:4 # 2.3 The test is: right-tailed two-tailed left-tailed Based on a sample of 60 people, the sample mean GPA was 2.25 with a standard deviation of 0.04 The test statistic is: {to 2 decimals) The critical value is: {to 2 decimals) Based on this we: O Fail to reject the null hypothesis O Reject the null hypothesisA medical equipment manufacturer believes that the proportion of faulty blood pressure monitors is greater than 0.11, the proportion stated by the supplier. We perform a hypothesis test at a significance level of 0.05 with the null and alternative hypothesis as follows: Ho: p = 0.11 and Ha: p < 0.11. A researcher inspects 150 items and finds 25 faulty ones. She gives a p-value of 0.01 in her analysis. Which of the following definitions is the correct interpretation of the p-value? O The probability of getting 25 or more faulty blood pressure monitors out of 150 if the true faulty rate is 0.11. The value that the z-statistic must be less than in order to reject the null hypothesis. The probability of rejecting a true null hypothesis.

- Use five-step hypothesis testing for each of the following problems. Number each of the five steps. You may use the traditional method or the p-value method. 1) Science fiction novels average 250 pages in length. The average length of 8 randomly chosen novels written by I. M. Wordy was 265 pages in length with a standard deviation of 35. At are Wordy's novels significantly longer than the average science fiction novel?
